What you will hate: the exposure to higher-than-average levels of estrogen than most oral contraceptives. Waiting a few months to get pregnant once the biological clock has rung. Putting up with the same side effects as taking an oral pill plus the risk of increased vaginal discharge, swelling and irritation. For injection users, there is also an increased risk for bone loss if you get the shot for more than 2 years.

Bottom line: if you are somewhat forgetful or have a busy lifestyle, are in good health and don't mind the wait to try to get pregnant after stopping your contraception, then an alternative hormonal application offers a few more conveniences that the traditional pill.

Implanted Devices (Copper IUD, IUD and Progestin, and Rod and Progestin).

What you will love: a long-term contraception solution with a 99% effectiveness rating. The rod can stay in place for 3 years; the IUD with progestin for 5 years; and the copper IUD for 12 years. You will also be hormone-free with the copper IUD. The rod is implanted in a less intrusive area under the skin in your arm.

What you will hate: upfront costs which can range from $500 to $1,000. There are common side effects, which can include cramps and irregular bleeding and uncommon side effects, which could include pelvic inflammatory disease and infertility. Overweight women will also be disappointed with the rod's reduced effectiveness for them.

Bottom line: if you can't envision the pitter-patter of little feet on the horizon, then an implanted device offers a long-term birth control investment.
